MOTOB -VEHICLE.

To all whom it may concern,

Be it known that We, HERBERT F.-DEPUE and CLARK A. Dnrun', citizens of the United States, and residents of Moville, in the county of lVoodbury and State of Iowa, have invented certain new and useful Improvements in Motonvehicles, of which the following is a specification.

The present invention relates to motorvehicles, and more particularly to the driving and steering mechanism thereof.

The invention has for its primary object the provision in a motor-vehicle of improved means for driving both axles of the vehicle to increase its tractive power.

Another object of the invention is the production in a motor-vehicle of an improved construction wherein both axles are driven and also adapted to turn laterally to guide the vehicle.

A further object of the invention is the production of an improved driving and steering mechanism, designed for use with the usual type of differential gearing and particularly adapted for driving and steering both axles of motor-trucks.

With these and other objects in view, the invention, consisting in the construction, combination and novel arrangement of parts, will be fully understood from the following description, reference being had to the accompanyin g drawings, which form a part of this application, and in which like characters of reference indicate corresponding parts throughout the several views, of which,-

Figure 1 is a plan of a tractor chassis constructed and equipped in accordance with the invention, the drive shaft being cut away and the drive-gear housings shown in horizontal section on a plane coincident with the axis of the drive-shaft; Fig; 2 is a fragmentary rear elevation. of the rear truck; and Fig. 3 is a fragmentary front elevation of the front truck of the vehicle.

Referring, now, to the illustrations, the main frame of the vehicle comprises side members, 4, the front portions of which are interconnected by cross members, 5.

The rear ends of the side members are interconnected and supported by a transversely disposed bolster, 8; and the front of the main frame is supported on a bolster, 'Z,

disposed longitudinally of the frame, and having its ends formed with journals, 8,

free to oscillate in hearings, 9, mounted under the cross members of the frame.

The center of each bolster is formed .with a cylindrical upright housing, 10,- supported by and alined coaxially with a cylinder, 11, formed on a differential gear case, 12, and free to tuft; on roller bearings, 13, interposed between the two cylinders.

The gear case, 12, incloses the usual. differential gear, including a bevel drive ring, 14:, and adapted to drive the axle shafts, rotating within the axle housings, 16, and having secured thereto the t action wheels, 1'1.

The bevel drive rings, 14%, are interm hed with bevel pinions, l8, carrie short drive shafts, 19, inclosed coaxially by the housings, 10, and 11, and journaled in roller-bearings, 20, retained by suitable bearing-cones, 21, inclesed by the housi s.

"r: 10, and entering the housings, iii.

The upper ends of the shafts, carry bevel-gears, 2'2, inclosed by enia portions, 23, of the bolste housings, and driven by bevel-pinions, 24, mounted on the ends of the main drive-shaft, 25.

The rear journal of the hollow','and incloses, coaxially, the adj acent end portion of the main drive shaft, journaled in roller bearings, 26, retained b a cone, 27, formed in the bolster ad acent the housing, 10.

Rearward displacement of the rollen bearings, 26, is prevented by a sleeve, 28, encircling the drive-shaft and inclosed by the journal of the bolster. Tue sleeve is provided with an annular flange, 29; which embraces and is secured by screws, 30 or otherwise, to a similar flange, 31, on the journaLof the bolster, which engages the rear side of the adjacent bearing 9. The said sleeve is provided with a. counter bore, 32, to freely inclose the end of the torsiontube, 3?).

The rear end of the drive-shaft, 25. is journaled in roller bearings. 34:, retained by a flanged bearing cone, 35, bolted or otherwise secured to the rear housing, 23, and freely inclosing the rear end of the torsion tube.

The main-drive shaft is represented as being continuous, and provided with a drive pinion, 35*.

The ends of each axle are pivotally connected by links, 36, with the opposite ends front bolster is and its housir and a different of the other axle, whereby the axles turn laterally in, unison.

3? represents the steering-gear shaft which is disposed transversely of the 1nain-' frame and has wound In opposite directions drive axle including an axle housing, a differential gear and its housing, a bolster disposed longitudinally of the main frame and supported by the difierential housing, the bolster being provided. with journals at its ends, hearings on thmain frame inclosing the journals, a drive shaft extending through one of'the journals, and a driving connection between the shaft and said gear- 2. In a motor vehicle, a main frame, front and rear axles, each including an axle-shaft a differential-gear housing, gear inclosed thereby and having a bevel drive-ring, front and rear bolsters supporting the main frame and having intermediate parts supported by the (inferential-gear housings, upright shafts rotat-ably incloseci by said parts, and upon which the latter housing-s are pi oted, beve pinions on the lower ends said shafts and engaged with the drive rings, bevelgears on the upper ends of said shafts, front bolster being disposed longitudinally of the main-frame and provided at its ends with journals pivoted on the main-frame, the rear one of said j|ournals being provided wlth an axial bore communicatino with said art a m 9 main-drive shaft disposed longitudinally of the mainframe, and having its front end masses portion inclosed by said bore, and bevelpinions on the main drive-shaft engaged with said" latter 'gears.

3. In a motor vehicle, a main frame, front and rear axles, each including an axle-shaft and its housing, a differential-gear housing, and a differentiaLgear inclosed thereby and having intermediate parts supported by the differential-gear housings, upright shafts rotatably inolosed by said parts, .and upon which the latter housings are pivoted, bevel pinions on the lower ends of said shafts and engaged with the drive rings, bevel-gears on the upper ends. of said shafts, the front bolster being disposed longitudinally of the main-frame and provided at its ends with journals pivoted on main frame, the rear one of said journals being provided with axial bore communicating with said part,

a main-drive shaft disposed longitudinally of the main-frame, and having its front end portion inclosed by said bore, bevel-pinions on the main drive shaft engaged with said latter gears, links connecting the ends of each axle with the opposite ends of the other axle, a steering-gear shaft, flexible links wound in opposite directions thereon,

and connected with the respective ends of.

one of said axles, and means for controlling said latter shaft, including a worm-Wheel on the latter shaft and a steering-post'having a Worm engaged with the Worm-Wheel.

a. In a motor-vehicle, a main-frame, front and rear axles, front and rear bolsters sup" porting the main-frame and supported by the axles, one of said bolsters being disposed longitudinally of the main-frame and provided with journals at its ends, bearings on the main-frame inclosing the journals, a drive-shaft disposed longitudinally of the main-frame and rotatable coaxially Within one of said journals and vehicle-oropelling' mechanism Within the bolsters actuated by said shaft.

In testimony whereof We have hereunto set our hands. a r
